Responsible sourcing: top 500 ranking

You can pack a great deal under the responsible sourcing umbrella – from businesses practicing sustainable procurement, specialists in environmental and ethical trading, thought-leaders in social impact, to those organisations sharing strategies and solutions.

The leaderboard is arranged by social media clout – those with massive influence undoubtedly sit nearer the top, indicating that meaningful interactions via social media channels count for a lot here.

The list is compiled by McClelland Media Ltd, and UK retail giant Marks and Spencer.
